PHILIP I-I. FIELDING, OF NEW YORK, N. Y.

ELECTRICAL RECEPTACLE.

SPECIFICATION forming part of Letters Patent No. 714,291, dated November25, 1902.

Application filed February 20, 1902. Serial No. 94,909. (No model.)

To aZZ whom it may concern:

Be it known that I, PHILIP H. FIELDING, a citizen of the UnitedStates,residing at the city of New York,in the borough of Manhattan andState of New York, have invented certain new and useful Improvements inElectrical Receptacles, of which the following is a full, clear, andexact description.

This invention relates to electrical receptacles, rosettes, and similarelectrical devices used at points where a branch circuit is taken offfrom a main circuit, the object of the invention being to provide asimple device which can be manufactured at low cost, which willeffectually cover naked portions of the wires at the joints, furnishmeans for inclosing the fuses commonly used in such devices, andaffording a construction which will in every way meet the requirementsof the rules of fire-underwriters.

With these objects in view my invention consists of a receptacle orsimilar device constructed in the peculiar manner hereinafter described,and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan of a receptaclecomplete and in connection with the main wire. Fig. 2 is a plan of thedevice with the cap removed. Fig. 3 is a side elevation of the basepart, showing a portion of the cap in dotted lines and portions of thebase broken away. Fig. 4 is a section on lines a: w of Figs. 1 and 2.Fig. 5 is a central transverse section of the cap. Fig. 6 is aperspective view of the cap with part broken away, and Fig. 7 is aperspective view of the base before the metallic portions are appliedthereto.

The form of device shown is that of an electrical receptacle adapted toreceive an incandescent lamp of the Edison type and to be used forsurface wiring with cleats. The receptacle consists of the two principalparts A and B, the former being the base and the latter the cap, bothbeing of porcelain or other suitable insulating material. The base is anelongated structure having grooves a extending across its ends for themain circuit-wires w and w, respectively. Between the grooves there is araised portion ct, to the center of which is fixed a cylindricalthreaded shell or socket b and a metallic center plate Z), adapted toengage,respectively,with corresponding parts on the neck of the lamp.The plate 12' carries a binding-screw 12 while the shell Z9 carries abinding-screw 5 located on the opposite side of the raised portion a.Each end of the raised portion a is provided with a deep groove 0, whichextends in an oblique direction from a point near the screws 1) or b tothe groove a for the line-wire. At the outer edge of these grooves andfixed to the perpendicular faces of the raised portion a by means ofscrews (1 are metallic clips d, which reach downward into the grooves aand are there provided with binding-screws d for gripping theline-wires, the insulation from which is removed for this purpose, asshown in Fig. 2. The grooves c furnish a passage for fusible conductorse and e, which extend from the binding-screws d, respectively, to thebinding-screws b and b and. thus complete the circuit from the two wiresto w to the two parts of the lamp-socket.

The cap Bis formed with acylindrical opening f, adapted to inclose theshell I), and with cut-away portions permitting it to fit down againstand over the edges of the raised portion a until it covers with its flatsurface f the corresponding surface 9 on the base and extends over thegrooves a. The cap is also provided with integral elongated plugs c',which are locatedin such a position that when the cap is adjusted to thebase they will enter and close the top of the respective grooves c 0,containing the fuse-wires, as clearly shown in Fig. 4, and thus providewhat is known in the art as an inclosed fuse. The passages for the fusesmight also be formed by perforating the raised portion a, and thus makethe inclosu re wholly in the base part of the receptacle; but on accountof the difficulty of molding the perforations it is considered betterpractice to form the grooves and close them afterward with the cap inthe manner described. In case the perforations were used instead ofgrooves the fuse-wire would have to be threaded through them, whichwould require a little more time in adjusting the parts for service.Having described my invention, I claim- An electrical receptacle orsimilar appliance consisting of a base part and a cap of insulatingmaterial, binding devices for conductors located at difierent points onthe base In Witness whereof I subscribe my signature in presence of twowitnesses.

PHILIP H. FIELDING.
